Peer to Peer Networks:

As we know the operating systems are of two main types –

1) Client OS and

2) Server OS.

Client OS are those which can manage only single user at any point of time. Examples of these are: Windows XP, Windows Vista or Linux client etc.

Server OS are those which can manage multiple users at a time. These are also known as Network Operating System (NOS). Examples of these are: Windows 2003 server, Windows 2008 server, Enterprise Linux server or Novell server etc.

So, when all the computers of a network have same (i.e. client) types of operating systems on them, then this type of network is called Peer to Peer network.

Client-Server networks: When at least one computer of the network has server type of operating system on it, then this type of network is called client-server network.
